Virginia is poised to pass a law banning the sale of fertilizer containing phosphorus, a major pollutant in the Chesapeake Bay and its rivers.

Lawns, parks, golf courses and other grass-covered areas cover 3.8 million acres of the Bay watershed. Most established lawns do not need phosphorus, but the majority of commonly used lawn fertilizers include phosphorus in their nutrient mix.

Once it goes into effect in 2013, the law will reduce an estimated 230,000 pounds of phosphorus pollution from reaching the Bay and Virginia rivers each year. This is 22 percent of Virginia's 2017 phosphorus reduction goal.

The law will also:

Require lawn service companies to apply fertilizer according to nutrient management standards.

Require that lawn fertilizer packages are clearly labeled with information on how to properly fertilize and reduce polluted runoff.

Bar the use of de-icers containing nitrogen.

A variety of groups, including the Chesapeake Bay Foundation, James River Association, Home Builders Association of Virginia and Virginia Association for Commercial Real Estate, supported the legislation.

The legislation was passed by the Virginia Senate and House of Delegates. It now awaits Gov. Bob McDonnell's signature.

When passed, Virginia will become one of nine states that restrict the use or sale of phosphorus in lawn fertilizer. Maryland and Pennsylvania are considering similar legislation.
